Key Parameters

Substitute Part Grouping Explanation

The MAX1259CPE+ qualifies as a parametric equivalent to the DS1259 based on the following critical substitution criteria:

• Identical package form factor: 16-DIP (0.300", 7.62mm)
• Matching mounting technology: Through Hole
• Identical functional category: Power Management (PMIC)
• Identical operating temperature range: 0°C ~ 70°C (TA)
• Identical moisture sensitivity level: MSL 1 (Unlimited)
• Same manufacturer ecosystem: Analog Devices Inc./Maxim Integrated
• Identical trade classification: HTSUS 8542.39.0001

The MAX1259CPE+ maintains full mechanical and electrical compatibility within the specified parameter set, enabling direct substitution in applications requiring the DS1259 footprint and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The MAX1259CPE+ is the designated substitute for the obsolete DS1259. Selection of the MAX1259CPE+ is based on:

• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance, providing regulatory advantage over the non-compliant DS1259
• Identical mechanical and thermal specifications enabling direct board-level substitution
• Maintained manufacturer support through the Analog Devices Inc./Maxim Integrated product line

For applications currently using the DS1259, transition to the MAX1259CPE+ is supported by matching package geometry, pin configuration, and operating parameters within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can the MAX1259CPE+ replace the DS1259 in existing designs?

A: Yes. The MAX1259CPE+ maintains identical package form factor (16-DIP), mounting type (Through Hole), operating temperature range (0°C ~ 70°C), and moisture sensitivity level (MSL 1). Direct substitution is supported at the board level.

Q: What is the primary difference between these parts?

A: The DS1259 is obsolete with RoHS non-compliant status, while the MAX1259CPE+ is an active product with ROHS3 compliance. Both share identical mechanical and thermal specifications.

Q: Are there packaging differences between DS1259 and MAX1259CPE+?

A: Both components use 16-DIP (0.300", 7.62mm) through-hole packaging. The MAX1259CPE+ is supplied in Tube packaging, while the DS1259 packaging specification was not provided. The package form factor and pin pitch are identical.

Q: Does the MAX1259CPE+ require PCB layout modifications?

A: No. Identical DIP package geometry and pin configuration eliminate the need for PCB redesign. Existing through-hole footprints are directly compatible.

Q: What is the inventory status for these parts?

A: DS1259 inventory: 1162 Pcs New Original In Stock. MAX1259CPE+ inventory: 1900 Pcs New Original In Stock.
